After successfully processing 100 or so entries, I started getting popup window every time a page loads. The window does not appear for pages being skipped. The top of the window says "External processing error". The body of the window says "The path is not of a legal form." I have tried restarting AWB and rebooting my PC: neither helped.
OS: Windows XP Home Edition version 5.1.2600
Version: 188.8.131.52 SVN 9356
Workaround: Click OK and continue processing. It doesn't seem to affect the output.
